Is there any truth to stories about a 'dry crescent moon' that 'holds water'?
The kind of moon referred to as 'holding water' is a crescent that appears to be leaning backward. Folklore is that matches drier weather. Such a moon is related to changes in the tilt of the earth's axis, the moons' orbit and variations in latitude. There's no evidence to suggest it has any impact (no science to support it either) on the weather. In fact, such a 'dry crescent moon' is most often seen during our winters...hardly a dry season.
